利用造纸废水恢复退化滨海盐碱湿地的方法
摘要：
本发明公开了一种利用造纸废水恢复退化滨海盐碱湿地的方法。该方法是用造纸废水浇灌待恢复的所述退化滨海盐碱湿地。上述方法中，所述造纸废水的COD值为200-1500mg/L，优选850-1200mg/L，最优选957mg/L。所述浇灌步骤中，所述造纸废水的浇灌深度为20-25cm。浇灌时间为每年的4月-6月，浇灌的次数为每月1-4次，优选2-3次。该方法能使退化盐碱湿地pH值略有升高，土壤养分含量提高，土壤微生物生物量碳显著增加，改善土壤的物理性质，增强了芦苇等植物群落的贮蓄土壤水分的能力，是降低土壤含盐量、提高土壤肥力的有效途径，具有很好的应用前景。
摘要（英）：

The invention discloses a method for recovering a degraded coastal saline-alkali wetland by using papermaking waste water. In the method, the degraded coastal saline-alkali wetland to be recovered is irrigated by using the papermaking waste water; the chemical oxygen demand (COD) value of the papermaking waste water is between 200 and 1,500 mg/L, preferably between 850 and 1,200 mg/L and most preferably 957 mg/L; in an irrigation step, the irrigation depth of the papermaking waste water is between 20 and 25 centimeters; and irrigation time is from April to June every year and irrigation is performed for 1 to 4 times every month, preferably 2 to 3 times. The method has the advantages of increasing the pH value of the degraded saline-alkali wetland, increasing the nutrient content of soil, remarkably increasing microorganisms and biomass carbon in the soil, improving the physical property of the soil and enhancing the soil water storage capability of plant communities such as reed and the like, is an effective way for lowering the salt content of the soil and enhancing the soil fertility and has good application prospect.
